The small GTPase rab5 has been shown to represent a key regulator in the endocytic pathway of mammalian cells. Using a PCR approach to identify rab5 homologs in Saccharomyces cerevisiae, two genes encoding proteins with 54 and 52% identity to rab5, YPT51 and YPT53 have been identified. Sequencing of the yeast chromosome XI has revealed a third rab5-like(More)
Ras-related, guanine nucleotide-binding proteins of the Ypt/Rab family play a key role at defined steps in vesicular transport, both in yeast and in mammalian cells. In yeast, Ypt1p has an essential function late in endoplasmic reticulum (ER) to Golgi transport, and the redundant Ypt31/Ypt32 GTPases have been proposed to act in transport through and/or from(More)
Rice blast disease caused by Magnaporthe oryzae is one of the most devastating fungal diseases of rice and results in a huge loss of rice productivity worldwide. During the infection process, M. oryzae secretes a large number of glycosyl hydrolase proteins into the host apoplast to digest the cell wall and facilitate fungal ingression into host tissues.

Osmotic stress is induced by several environmental stresses such as drought, cold and salinity. Osmotic stress may finally leads to oxidative damage, ionic imbalance and growth inhibition in plants. Gene expression analyses indicated that ZAT10 transcription factor, a novel substrate of Arabidopsis MPKs, could be induced by environmental stresses that(More)
